Farin is a teenage citizen of Eternos, who has a pet Gronk named Armi. He is the boyfriend of Karil, who is in awe with He-Man. Foolishly jealous of He-Man, Farin devises an almost genius-like plan to fool Karil into believing that he and He-Man are one in the same, in the hope of impressing her. Farin is overjoyed when Karil believes him to be He-Man, but his joy, bravado and confidence soon fade away when he is captured by Modulok. After he is rescued, Karil assures him that she like him the way he is and urges him to stop pretending to be He-Man.
